Specification of Letters Patent.

Patented July 28, 1914.

Application filed February 15, 1913. Serial No. 748,561.

To all whom it may concern Be it known that I, ARTHUR D. MARCOTTE, a citizen of the United States, and a resident of Eunice, in the parish of St. Landry and State of Louisiana, have invented an Improvement in Oil-Burners, of which the following is a specification. Y

My object is to provide an improved device for burning crude or low-grade oil, so as to effect its complete combustion without production of soot or smoke which are frequently incident to the burning of oils of this character.

In carrying out the invention I provide means for vaporizing water and mixing the vapor or steam with the oil which is fed in under pressure. The vapor or steam is generated in a coil located in the fire-box of a cook-stove, furnace or other heater, and a feed pipe and return pipethe former provided with a check valve-connect such coil with the water tank or holder, so that the water therein is subjected to steam-pressure corresponding to that existing in the coil. The oil is fed to the burner proper and atomized by the steam dis-charged through a nipple and which effects the feed of oil, upon the induction principle which is utilized in the well known water-injectors of steam boilers.

In the accompanying drawings, Figure 1 is a perspective view of the entire apparatus. Fig. 2 is a plan view of a portion thereof. Fig. 3 is a side view of a portion of the apparatus with part in section. Fig. 4 is an enlarged longitudinal section of a portion of the burner to which the oil and steam are supplied and by which they are fed to the burner proper.

Referring in the first instance to Fig. 1, the numeral 1 indicates a water tank or holder set vertical and provided with a water gage 2, a pressure gage 3, and a relief valve 4, which parts have no novelty in construction and arrangement.

A pipe 5 is attached to the bottom of the tank 1 and serves to convey water into the coil 6 which, in practice, is arranged horizontally in the fire-box of any form of heater that may be employed. The pipe 5 is pro vided with a stop-cock 7 and a check valve 8, the latter serving to prevent the refiow of water or steam from the coil back to the tank.

Pipe 5 is connected with the lower leg of the coil 6, and the upper leg at the latter is in turn connected with a vertical steam pipe 9 whose upper end extends to the burner 12 while its lower portion 9 is extended downward and connected by pipe 9 with top of water tank 1 said pipe?) is provided with a check valve 10 and a trap or condenser 11, as shown. The diameter of the condenser is about four times greater than the pipes 9, and it is located at about half the height of the coil; that is to say, at about mid-way between the legs of the coil. Owing to such location and size of the condenser,.it serves to prevent the filling of the coil with water when pressure is ion the tank.

The vapor or steam pipe 9 is further connected by a pipe 9 with the enlarged chambered base portion 12 of the burner, it being provided intermediately of the coil and burner with a stop-cock 18. An oil supply pipe 14 is also connected with the burner body 12 and provided with a stop-cock 15.

As shown in Fig. 4:, the burner body 12 is provided with a central partition 16' and the steam and oil pipes 9 and 14 connect with the respective chambers formed on opposite sides of the said partition. The outer end of the burner body 12 is provided with a screw-plug 12 which permits convenient cleaning of the adjacent chamber and also insertion and removal of the steam feed pipe 17. This pipe is constructed of copper and is held in what may be termed a nipple 18 that screws into the partition 16. The outer end of this nipple, which is preferably constructed of brass, is chambered and provided with a filling of hard solder through which the copper tube 17 projects. The said tube 17 terminates a short distance from the end of the elongated tube 18 forming an attachment of the body 12, and it will be apparent that when oil and steam are simultaneously admitted to the burner body by pipes 9" and 14 respectively, the current of steam discharging from the feed tube 17 will induce a current of oil in the tube 18, as shown by the several arrows in Fig. 4. The oil is thus atomized and fed along with the steam and both are discharged in intimate mixture into the large perforated burner proper 19 which extends alongside the coil 6 within the firebox of the heater to which the apparatus is connected. There is thus a uniform discharge of steam and a uniform feed of oil, and the flame or combustion is steady without the flickering incident to burners of this general clasa Although automatic feed and convenient regulation of the same are incident to this burner, the latter is very simplein construction and may be cheaply manufactured.

The perforated cylinder or burner proper 19, which may be made of iron or burnt clay,

tends to mufiie the roaring which would be otherwise incident to the combustion of the oil. The mufiling referred to is due to the perforations in the cylinder.

In practical operation of the apparatus, a tray is furnished for the burner to hold oil in the base of the furnace or fire-box and this tray is filled with wood ashes, thus serving as a WlCkIEOI the oil let into it and ignited. By such ignition, the coil is soon heated, say in about. five minutes, and then the valve 7 of the water pipe being opened, steam is generated in the coil which enters the tank -1 through pipe 9 so that pressure is applied to the water in: the tank. Now, the oil. valve 15 is opened and the pressure of steam admitted to the burner proper will indueea current .ofoil and. atomize-it at the same time. Thus, by manual; manipulation of the valves of the several pipes, the feed I of steam and oil may be graduated at will. As a rule, the pressure of steam will be about twenty-five pounds for cooking purwith the upper leg of coil, the lower portion of said pipe extending below the junction with the coil and being connected with the top of the tank, and a condenser and check valve interposed in the steam pipe, as dey scribed.
